' adapted to be moved when not in useto a position alongside ot anotherWall that stan( s at right angles to the Wall that has the doorway.`rThe two sections of overhead track that lie' ad] acont to suchte/'oWalls are of course connected by a curved track section so as to 'fornia continuous path for the Wheels of the carriages that travel on the tworails oi the track and 'from which carriages f the door suspended., ltis very desirable, oit course, that such curved `connecting` tract;section or corner portion should have as short a 'radius as possible,not only to allow the door to be brought conveniently close to eitherwall without undue length of travel ot' the said wheeled carriages butalso,` that said curved connecting section shall not extend out into therooni to any great err` tentand thereby constitute adisiipjureuient andalso a possible obstruction to the nioying ot certain tall articles inorV adjacent to the corner ot` the room Where such curved connection islocated. The side Walls oi"4 the curved connection hayeheretotore beenspaced apart to the same extent as the two inain straight tracksectionstha-t connect with it' andthe result has been that as thecarriages passed through it their wheels would, by reason ot the shortradiuso'f that section ot the track, corne into grinding; contact withthe sidey Walls thereof and seriously interiore with the easymovernentoi the door :trono one of its said positionsto the other. Variousexpediente have been de! vised to obriate this objection, anion@` Whichmay be cited the construction shownin Let` ters Patent No, 1,188,482,`granted plune 27, 1.916., upon an application tiled by me. @While theconstruction there shown has been found satisfactory it involvesconsiderable incre efr-i pense that is desirable in connection with the`installation ot (loors in' seine situations, mving to the addition tothe wheeled oarriages of extra parte,` i

lt is the objectofniy present invention to te .i incnts in theJtrackitselth rather than in the wheeled carriages that run thereon, and,brietiy and broadlyv stated, i accomplish this by leaking; the curvedconnecting i-neniber of the `track 'Wider than the straight acksetitioiis that connect th with (except the end portions oit such straht sections that abut against the ends ot the curved section) and i htlytapertorniing such straightsections si D nig `'rroin end to end so `thatat their inner and Wider ends they will accurateiy register or aigi'n,respectively, with the ends olE the wide curved corner seien, all asshown in the drawing. and inore particularly described hereinafter. l fin the drawing-1 y t 'i .is a top view.r partly in 4horizontal section,oit a trolley track embodying my invention; 4

.,-teterring to `the several `figures of the drawings, 5 indicates acurved track section-,adapted to be located adjacent to the corner oi!`a roonr and constituting a portion oli a track that `extends alongopposite two we ls ot' a rooni in one ot' which will be 'termed adoorway yadapted to be .closed by a sliding,v door, and against theother Wall which stands at right angles thereto such `door is adapted"tobe moved When the doorway is'uncoyerecl. rThis curved track sectionin the construction shown (see Fig. 3) itorxi'ied ottwo side 5 placed adistintey apart and parallel With each other, the lower inarffinal.portionsoif which are bent inward and upward toitorin ordinary railsior the wheels of a carriage to run upon, and the upper vmarginalportions of which Walls are iii \ifa`i lly turned vand connectedtogether, such connection in the constructionshown being by anoverlyingpiece of sheet metal 5l spot-Welded thereto. The track structuredescribed is of ordinaryY forni in cross-section except that such tracksare usually 'formed troni a single piece. Un account ot the curvaturesuch 2 thc object-ion mentioned by improvei corner pieces of thiscross-section are ordinarily termed by casting7 but by making the twowall members 5a separately and con-` necting them togetherby the plateebl ani able to make them without diiiiculty of sheet metal as in the caseof straight sections of track, which is of considerable advantage as thestructure is, of course, lighter and the track as a whole is moreuniform in appearance than where one part is a casting and the otherparts are ont sheet metal. This curved section 5 is intended to be widerthan the straightaway sections that `connect with it in order that moreroom mayy be provided for the wheels, and thereby avoid the liability socommon in corner sections of short radius of having the edges of thewheels contact with and grind against the side walls or against theupturned lips Aof the rails, or both. 6 indicates a straightaway sectionof track which in cross-section is substantially,7 like the curvedsection, but, as clearly shown in F ig. 2, is made from a single pieceotsheet metal, as is usual. The only departure from ordinary practice inthe construction of such trackscction 6 is that it is made graduallytapering throughout its length so that at its inner and larger end it isot'a width` to abut against and register or aline with the ends ot thecurved section 5. At its other and smaller end it is of the same widththat track ot this description is ordinarily made so that it anothersection ot' track of said ordinary width is connected with'it, as ishere shown to be the case,- the abutting ends will aline or register asusual. Such an additional track section as `last referred to isindicatedby 7. They tapering ofthe track section 6 is formed by makingthebends at the upper and lower ends of the side walls of the two parts511--5a along slightly diagonal lines instead of along parallel lines'as in` the case ot the forming of an ordinary track .section such asthat indicated by-7, The

bending up oit the lips at the inner edges of the two rails of the trackwill be along parallel lines, as usual, so that such rails will remainthroughout the length ot the tapered sections evenly spaced apart asusual.

A tapered section 6 will abut against each end ot' the curved cornersection 5, ot course, and., while it is possible to make such taperedsections long enough to constitute the straightaway portions yot' thetrack in and byl themselves, yet it will be found better practice to usesuch tapered sections only as means interposed between the curved cornersection and a section ot the usual width such as indicated by l'.Ordinary sustaining brackets adapted to be secured. against a vwall willbe applied to the track. In the construction shown two brackets 8 areindicated as supporting the adjacent end portions of the curved section5 and the tapered sections 6, such brackets being of the usualconstruction except that they will be' `given a slight taper to makethem conform to the tapering end of the section 6 so as to thereby holdthe abutting parts snugly in proper alined position. @ther brackets,such as 9, are shown for connecting togetherl the abuttinglends of thesections 6 and T, and they will, oi course, also be properly shaped tosnugly receive and hold such ends. To prevent endwise movement thatwould allow withdrawal of a track section .trom its supporting bracket lpreferably indent the upper wall of the track as at l0, into whichindentations the ends of bolts l1 pass, such bolts being screw-threadedthrough the upper walls Vot the brackets.

y my invention l provide a track that incorporates in it at the bend ashort radius section of a materially wider width than is ordinarilyprovided, and which, therefore, allows a tree sidewise turning ot thewheels of a carriage on the track without such wheels being hampered intheir rolling movements by hard scraping against the Se (UU sides oitthe section or the upturned lips at the inner edges of `the track.Furthermore, by making the section 6 of the track tapering yas describedl am able to provide a construction wherein notwithstanding thedifference in vwidth between the curved piece and the `straight sectionsof ordinary size I am able to connect these several parts together insuch manner as to preserve the goed appear-` ance ot the track as awhole and at the same time provide for the perfect connection ot theseveral sections of the track so as to insure the easy ruiming ofwheeled carriages thereon.

"What I claim as my invention and desire to secure by Letters Patent,is-' l. In a trolley-track, the combnationo" a curved track section andanother section that abuts at one endy against an end of the curvedsection, each ofsaid sections comprising a wall member and a railmember, the rail member of the curved `section being materially widerthroughout its length than the rail `member ofthe other section toobviate binding of the wheels of a.l trolley against the wall of thecurved section when a trolley is moving therealong.

.2. In a trolley-track, the combination ol a curved track section andanother section that abuts at one end against an end et the curvedsection, each of said sections compris ing a wall member and a railmember, the rail member of the curved section being materially widerthroughout its length than Athe rail member ot the other section toobviate binding of the wheels ot a trolley against the wall of thecurved sect-ion when a trolley is moving therealong, and the rail memberoi said second-namedv section gradually. de-

of substantially the same Width as the width of the i curved section andagainst which curved section said end abuts, the lopposite end of saidsecond-named section being of less width than the curved section.

` 6; A curved double-rail hollow track section comprising in combinationtwo spacedapart sheet-metal wall members having `inwardly-turnedmarginal rail portions and inwardly-turned upper marginal portions, anda plate secured to said upper turned portions to hold said wall memberstogether.
